REVIEW
A Wozniak-Rito, I Zalaudek, L Rudnicka
Dermoscopy is widely used in dermatological practice. The method increases the accuracy of basal cell carcinoma (BCC) detection. Pigmented and nonpigmented variants of basal cell carcinoma present different dermoscopic features. Specific dermoscopy criteria have been recognized in different subtypes of BCC. Differentiation of superficial BCC from other subtypes is the most important issue, as it may determine further management decisions.

BACKGROUND: Several dermoscopic and in vivo reflectance confocal microscopy (RCM) diagnostic criteria of lentigo maligna (LM)/lentigo maligna melanoma (LMM) have been identified. However, no study compared the diagnostic accuracy of these techniques. OBJECTIVE: We evaluated the diagnostic accuracy of dermoscopy and RCM for LM/LMM using a holistic assessment of the images. METHODS: 223 facial lesions were evaluated by 21 experts. Diagnostic accuracy of the clinical, dermoscopic and RCM examination were compared...

BACKGROUND: While substantial dermoscopic analysis of melanocytic lesions has been performed, dermoscopic characterization of cutaneous lymphoid proliferations has been limited. Cutaneous lymphoma, particularly early mycosis fungoides (MF) and its variants, is often challenging to clinically and pathologically distinguish from inflammatory processes of the skin. This study aimed to survey the dermoscopic findings of cutaneous lymphomas and to discern whether any patterns might potentially serve as specific signatures...

Vascular structures of skin are important biomarkers in diagnosis and assessment of cutaneous conditions. Presence and distribution of lesional vessels are associated with specific abnormalities. Therefore, detection and localization of cutaneous vessels provide critical information towards diagnosis and stage status of diseases. However, cutaneous vessels are highly variable in shape, size, color and architecture, which complicate the detection task. Considering the large variability of these structures, conventional vessel detection techniques lack the generalizability to detect different vessel types and require separate algorithms to be designed for each type...

REVIEW

Actinic keratosis represents the earliest manifestation of non-melanoma skin cancer. Because of their risk of progression to invasive squamous cell carcinoma, an earlier diagnosis and treatment are mandatory. Their diagnosis sometimes could represent a challenge even for expert dermatologists. Dermoscopy, confocal laser microscopy and optical coherence tomography could help clinicians in diagnosis.

Dermoscopy has been documented to increase the diagnostic accuracy of clinicians evaluating skin tumors, improving their ability to detect skin cancer and better recognize benign moles. However, dermoscopically "false positive" and "false negative" tumors do exist. False positive diagnosis usually leads to unnecessary excisions. False negative diagnosis is much more dangerous, since it might result in overlooking a cancer, with severe undesirable consequences for the patient and the physician. Therefore, management strategies should mainly focus on addressing the risk of dermoscopically false negative tumors...

Acral pigmented Spitz nevi are seldom reported in the literature. We report a new case on the palm of a 4-year-old girl that demonstrated correlation between features observed on dermoscopy and reflectance confocal microscopy (RCM). Histopathology revealed a benign intraepidermal Spitz nevus with transepidermal elimination of melanocytes that showed on RCM as focal atypical bright cells concerning for malignancy. This case is one of few reports in the literature combining dermoscopy, reflectance confocal microscopy, and histology for an acral Spitz nevi, which are rarely evaluated by RCM given the thickness of the stratum corneum in acral sites...

BACKGROUND/OBJECTIVES: Arteriovenous tumour is a distinct, benign, acquired vascular lesion that can be misdiagnosed. METHODS: A dermoscopic examination of 39 cases of arteriovenous tumours collected from four Spanish hospitals was performed to evaluate specific dermoscopic criteria and patterns. RESULTS: The most common structures found were vascular, 95% of cases (37/39); 90% (35/39) were non-arborising telangiectasia. All the lesions except two (95%) had a homogeneous pigmentation background that was red in 30 cases (77%), bluish-red in three (8%), brown in two (5%) and blue or multicoloured in one case each...

BACKGROUND: The genetic basis of melanoma affects its clinicopathological characteristics and increasingly influences its management. BRAF-mutated melanoma may present with specific dermoscopic features.

BACKGROUND: Specialised surveillance using total body photography and digital dermoscopy to monitor people at very high risk of developing a second or subsequent melanoma has been reported as cost effective. OBJECTIVES: We aimed to estimate the 5-year healthcare budget impact of providing specialised surveillance for people at very high risk of subsequent melanoma from the perspective of the Australian healthcare system. METHODS: A budget impact model was constructed to assess the costs of monitoring and potential savings compared with current routine care based on identification of patients at the time of a melanoma diagnosis...

BACKGROUND: Abruptness of pigment patterns at the periphery of a skin lesion is one of the most important dermoscopic features for detection of malignancy. In current clinical setting, abrupt cutoff of a skin lesion determined by an examination of a dermatologist. This process is subjective, nonquantitative, and error-prone. We present an improved computational model to quantitatively measure abruptness of a skin lesion over our previous method. To achieve this, we quantitatively analyze the texture features of a region within the lesion boundary...

BACKGROUND: Dermoscopy of morphea and cutaneous lichen sclerosus (CLS) has been described by various studies, with none of them considering variability according to clinical phases and investigating dermoscopic-histological correlations. OBJECTIVE: To evaluate dermoscopic features in general and according to clinical stage, identify possible distinctive dermoscopic clues, and assess dermoscopy accuracy in detecting subclinical alterations in morphea and CLS. METHODS: A representative dermoscopic image of target lesions was evaluated for the presence of specific features, correlating them with clinical subtype (inflammatory, inflammatory-sclerotic, sclerotic, or sclerotic-atrophic)...

Tinea capitis (TC) is an infection of the scalp, most often observed in pre-school or early school ages. Diagnosis of TC is based on clinical signs and laboratory examinations (direct microscopy and culture). Dermoscopy is a non-invasive diagnostic technique with an already established role in the evaluation of skin tumors, and with a gradually expanding application also in the field of inflammatory and infectious skin diseases.

Acral melanoma (AM) is a rare subtype of cutaneous malignant melanoma found on acral skin, primarily on the soles of the feet. Although rare, it is the most common subtype of melanoma found in patients of African or Asian ethnicity and has a poor prognosis, often because of the more advanced stage of presentation at diagnosis. In the second of this two-part series, we review the clinical presentation, histopathology, diagnosis and management of AM. Clinically, AM presents as a variegated lesion with blue-black pigment and irregular borders on acral skin...
